#778 – Animating a Scale Transform

Here’s another example of an animation of a 2D transform.  In this case, we animate the scale of the object so that it grows larger and smaller and then repeats the behavior.  This results in a sort of pulsating button.

    <Grid>
        <Button Content="Ship via Wells, Fargo &amp; Co." HorizontalAlignment="Center" VerticalAlignment="Center"
                Padding="20,10" FontSize="16"
                RenderTransformOrigin="0.5,0.5">
            <Button.RenderTransform>
                <ScaleTransform x:Name="scaleTransform" ScaleX="0.98" ScaleY="1.02"/>
            </Button.RenderTransform>
            <Button.Triggers>
                <EventTrigger RoutedEvent="Button.Loaded">
                    <BeginStoryboard>
                        <Storyboard>
                            <DoubleAnimation Storyboard.TargetName="scaleTransform"
                                             Storyboard.TargetProperty="ScaleX"
                                             From="0.98" To="1.02" Duration="0:0:0.3"
                                             AutoReverse="True" RepeatBehavior="Forever"/>
                            <DoubleAnimation Storyboard.TargetName="scaleTransform"
                                             Storyboard.TargetProperty="ScaleY"
                                             From="0.98" To="1.02" Duration="0:0:0.3"
                                             AutoReverse="True" RepeatBehavior="Forever"/>
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger>
            </Button.Triggers>
        </Button>
    </Grid>
